You can attach, preview and edit Office documents, PDF files, images and videos attached in a Yammer conversation. Open in full-screen preview, or edit using Office Online, right from the conversation or the Files list. You can even co-author Word, PowerPoint, and Excel files.

Note: Because the Yammer preview and edit function uses Office Online, it works only when the attached files are file types compatible with Office Online, including Word documents, Excel spreadsheets and PowerPoint presentations. You can preview PDF files in Yammer, but editing is not available.
